Have you ever had a a pre-beta version installed? Did you revert to the v12.6 release version after a full clean-out of your V14Beta

I think there is to be some, perhaps minor, revision of the licensing system with the release of V14 - just as a wild guess - in that circumstance am not sure if it is even possible during the beta stage to licence V14Beta as the first installed version?? There are no V14 licences available yet.
